Improvement in heating and soldering gun-barrels



VUNITED STATES 7 ETHAN ALLEN, OF WORCESTER, MASSACHUSETTS.

PATENT OFFICE.

Specification forming part of Letters Patent No. 55,596, dated J une 19,1866.

To all whom it may concern.:

Be it known that I, ETEAN ALLEN, of Worcester, in the county ofWorcester, State of Massachusetts, have invented a new and Improved Modeof Heating and Soldering Gun-Barrels; and I do hereby declare that thefollowing is a full and exact description of the same, reference beinghad to the accompanyin g drawings and letters of reference markedthereon.

Figure 1 is a perspective view of the reboX and bench or table; Fig. 2is top View of the grate; Fig. 3 is a sectional View of a single nozzle;Fig. 4 is a top view of a pair of barrels clamped ready for soldering,and Fig. 5 is a side view of a clamp.

The nature ot' my invention consists in so arranging a fire-box inconnection with one or more gunbarrels that the blaze is blown entirelyTthrough them, heating sufficiently for tinning and soldering; also, the.mode in con- Iinin g the barrels together.

That others skilled in the art may make and use my invention, I willproceed to describe its construction and operation.

A is the tire-box; B, the grate; C, the lower door or opening; D, theupper cover to the box; E, the wind or blow pipe; F, the double nozzle;G, the single nozzle; H, the table; I, the gunbarrels, and J the clamps.

The fire-box Ais divided near the center, as shown by the dotted lines,Fig. 1, and is provided with a grate, B, as seen in Fig. 2. The grate Bis connected to the door G by a link in such a manner that when the doorG (which is hinged to the front side ot' box A) is fastened in place thegrate B is also secured in the right position for use, and when thelower door, C, is let down to discharge the ashes the grate B is alsolet down, discharging the contents of the upper part of tire-box A. Thelire-box A and table H are supported ou suitable legs,

' (not seen in the drawings.)

The operation is as follows Fire being built in the upper part of themetallic irebox A upon the grate B, and the single nozzle Gr beinginserted into the box A in place of the double one, F, which is removedfor the time being, a single barrel is placed upon the blocks 7L and h'of the table H and slid over the tube or nozzle G. Wind is nowcommunicated through the pipe E from the bellows, and is forced throughthe grate B to the iire, and the blaze and heat of the lire are blownthrough the nozzle Gr the whole length of the barrel through the inside,heatingit sufficiently to tin the side. Having tinned the sides of twoof these barrels, they are put together and the ribs placedin the rightposition, when they are securely fastened together by clamps J, whichare provided with set-screws 7c and springs n. The nozzle Gr is nowtaken out of the tire-box A and the double nozzleF is put in its place,when the two barrels I are put upon the blocks h and h of table Handconnected with the nozzles, as before, when the blaze is forced throughboth of these barrels at the same time, hea ting them sufficiently tosolder. The solder is now applied and the wholeis secured rmly together,`the degrees of heat being regulated by letting more or less blastthrough the pipe E by a suitable slide made for that purpose. The clampsare now removed and the operation is repeated as before.

The great advantage of this mode of putting barrels together over theold plan of confining them with wires and heating over a tire or byheated plugs will be apparent to any one skilled in the art, for thebarrels are heated regularly and very quick through their entire length,and are in a position for the workman to handle conveniently, and theclamps can be used an almost endless number of times, thereby saving nosmall expense for wire, as well as time, where barrels are manufacturedlargely.

Having fully described my invention, what I claim therein as new, anddesire to secure by Letters Patent, is

1. The mechanism, substantially as described, for heating and solderinggun-barrels by blowing the heated blast through them.

2. The clamps J, composed of set-screws and springs, substantially asdescribed, for holding gun-barrels while being soldered.
